Ideation(BSSI).30 of them who had the highest scores of insomnia, nightmare and suicide ideation, were selected.
Then they were randomly assigned to experimental and control groups. For each of 15 persons of experimental
group, IRRT was carried out weekly(7 sessions).Then both groups answered the ISI,DDNSI and BSSI inventories
